This invention relatesto machines forV operatingupon: the heels oitl boots; and shoes, andi, whileit relates moreY particularly to `machines. for inserting.` attaching nails by which to. secure thef latteri to shoes, some of its` features.mayy be embodied with good: advantage in machinesl for priclring` heels preparatory to the insertion, of such nails.

lit islan object of theinvention to provide ai machine of: the general character above suggested which. shall be of an-` improved and simplified construction and.y shall' operate` with accuracyV to perform the operations requis-ite for inserting nails inclined.` with respect to the surface ot the heel which they iirst enter.

In many classes of work it: is found ad-` vantageous to drive the attaching nails inclined longitudinally` ot the heel from the tread surface to the heel seat surface as in this way the heels: may be secured more firmly than when the; nails are driven perpendicularlyl This isv particularly true in dealing with tapering; heels or those nndercut at the breast; Attaching nails driven `penn:endicularly to the tread; tace of such heels` would leave the rear portion of the heel seat litt unsecuredand: would be likely topass so` close to its forward edge as to interferev witlr the subsequent breasting operation.

With. a view' to simplifying machines` heretofore used in thisclasszof work an im'- portant feat-ure ofi thelinvention consists in providing heel pressing members relatively movable inra direction;substantially at righ-t angles to= the work engaging.; faceV of one member,together with` a, head movableJ in thev same direction and: carrying awlsor` drivers arranged to move in an inclined path when operating upon theV heel held under pressure: l-'n the machine herein disclosed. this` result' isobtained by mounting driven blockf to slidetransverseiy in= ways formed in the movable head and providing :inclined driver passages 1n` one of the heel *pressing members through which the iiiclined: drivers are arranged to work. As

ithe drivers traverse the guiding passages :the driver block is lett free to slide transversely on the headY permitting the drivers to` follow the path determined by the passages.

The present invention may be utilized ,Withl particularly good results in a machine having: a.y multiple gang of inclined drivers `:arranged to form several: horseshoe-shaped -nailings of different sizes. istruction` the increasedf number of inclined drivers renders the transverse movement of ln such conthe driver block substantially positive and eliminates the tendency to bend which.` may appear where drivers of less number are employed. rlhis ltendency to bend is caused ,by the fractional resistance to transverse movement. ot the driver block. It will be understood that in practice only one horseshoe-'shapednailing in the die plate is loaded with nails andi that those drivers which do noty encounter nails in the driver passage kare equally as effective in producing the {transverse movement of the driver plate as :those which are alsoA effective in driving.

The driver passages-may have a substan- Vtially uniform inclinationV or, ifl it is desired fto=drive someoi2V the attaching nails with an outward asi well as rearward inclination, ythe corresponding driver passages may be Vmade-to diverge laterally, the drivers being permitted to deflect laterally to follow these passages by reason oftheir resiliency.

An important feature of the invention, ac-

cordingly, consists in the combination, with aV heel? pressing member having inclined and divergent driver passages, of a driver block iree to move transverselyl during the attachvling' operation and drivers Ytree to spring or bend laterally.

Inv those constructiens where it is` neceslsary toV draw the drivers out of the guiding `ypassagestopermit attaching nails to be supplied tothe passages itisimportant to control the'path of the drivers until their ends Ahavebeen again' entered inthe guiding passages.

To this-end another fea-ture of" the invention consists in providing guiding means for controlling the position of the driver gbl'oclr and' drivers uponV the head` when it has moved sufficiently from the work pressingV members to carry the ends of the drivers out of the passages, said means being arranged to Vrelease the driver block and leave the drivers free to follow the path of the passages when the head has again moved sufficiently to enter the ends of the drivers in the passages. In the machine herein dis- Y closed the driver block is carried by a plate having an aperture slidingly fitted to a sta? tionary guide pin which terminates at a distance from the ends of the guiding passages substantially equal to the length ofthe drivers. Preferably the guide-pin is removably mounted in a stationary bracket so that when it is desired to remove the driver block from the head it may be conveniently released by sliding the guide pin out of engagement with the plate. Y

For purposes of illustration the present invention will be described as embodied inV a nailing machine of the type shown in my prior Patent No. 446,885 to which reference vmay be had for further details of construction., althoughit is to be understood that ,the invention is not limited to this type of heel nailing machine but is of general ap plication.

In the accompanying drawings,-F1gure 1 is a rear view in perspective of a preferred embodiment of the invention; Fig. 2 is a sectional view of the operative parts of the machine showing the position of the drivers at the end of the driving stroke, and Fig. 3 is a sectional view at right angles to that of Fig. 2, showing the drivers retract-ed.

The transversely extending bar 12, which constitutes the die plate is rigidly attached to part of the frame of the machine, and is provided with a multiplicity of driver passages having a substantially uniform inclination toward the rear of the machine. The cross head 14 is secured to and actuated by Vthe side rods 16 to whichV a vertical recipro- Vcation is imparted by any suitable mechanisin. On its lower side the cross head is provided witha square progecting portion to which is rigidly attached a block 2O pro vided withl oppositely disposed ribs which form a horizontal guideway. Slidingly mounted in said guideway is a plate 22 carrying on its lower surface the Vdriver 'block24a In'the driver block are mounted a number of drivers, one for each of the driver guiding passages in ClieV plate 12.

vThe drivers are set in the driver block at a longitudinalV inclination corresponding to that of t-lie driver passages 13. The drivers Vand passages are arranged to form a number of diiferent sized horse shoe shaped nailings,tlie machine being adapted to attach heels of different sizes by supplying attaching nails to one orvanother of the series of driver passages.V

Suitable means are provided for guiding Vthe drivers in a vertical pathrwhile they move toward or from Vthe 'driver'passages inY which the rods 16V reciprocate. VThe guide .Y

pin 32 is provided with a collar 33 which rests on top of the socket 34. is adjustably secured to the guide pinV 32 by a set screw; the pin is held in the socket by a set screw or other convenient means and is tapered'at its lower end in order to enter more readily the aperture in the ear30 and center the carrying plate 22 when the `cross head is elevated. When it is desiredV to re-Y move tlie driver block from the head 14 for any reason the pin32 may be loosened and engages the ear 30 whereupon the platev22 and driver block ai'e free to be drawn out of the guideways in the block 20. The vertical position of the guide pin is gaged by the collarv 33, the latter being so setas'to hold rlfhe collar 33' sal drawn upwardly in its socket until it dis- Y the end of the pin above the surface of the die platea distance equal to the length ofthe particular drivers being used Below the die plate 12 is mounted, a jack 40, upon which theY shoe lto be Vheeled is placed. The jack may be moved out of alinenient with the cross Vhead to permit a ofV this kind. TheY jack kis also movable Vshoe to be jacked, as is common in machines` vertically toward and fromtlie die plate 12 in order that the heel to be attached maybe v subjected to Vpressure preliminarily toV the;

nail driving operation. Any suitable mech anism may be vutilized tofeffect'the verticalV movement of the jack, a preferred construction being disclosed'in my prior patentV above identified. Side clamps 4t2 are prothe jack.

lf it is desired to cause some of the at.-`

taching nails to' diverge as they are driven, as would be the case shouldgtheheelsto be attached be tapered or undercut at the sides,

the outer driver'passages 13are made vto diverge downwardly, as shown inV Fig.v3, in

addition to their rearward inclination.V The Y i corresponding drivers in traversing the divergent passages spring or bend outwardly as suggested by the dotted line positionl of the driver 26r in Fig. 3.` On being with- Y drawn from the passage, however, these drivers reassume their normal'position by ii5 1 Y videdfor properly positioning the shoe upon f j Atially parallel with the others.

i invase@ reason of t'heirresiliency and 'stand substanf nails are 'then inserted in the proper 'series of driver passages and povver is 'applied to Ward movement of ers and driver block are bodily shifted tothe machine. The jack is thereupon `forced upwardly putting the Worlrunder pressure and the cross headlt is moveddovvnivardly. As the cross head descends Vthe apertured ear of the carrying plate 22 slides downvvardly upon the pin 32, thus guiding the driver block and drivers in a vertical path. When the cross head has moved suliiciently to enter the ends ofthe drivers in the driver passages the ear 30 has moved below the end of "the guide pin "r-el'earsingthe driver block so that the `advancing drivers are free to follow the path determined by the driver passages. On the continued downthe crosshead the idrivivard the rear of the machine asa result of the co-action ofthe inclined drivers and the inclined passages, theV resultant movement being in a path vparallel to the direction of the driver passages and the attaching nails are driven fromth'e passages int-othe heel blank and sole in the samedirection, being clenched toward the rearof the shoe upon the surface of thefjack. yOn the upward movement of thecross lheadjthe driverpassages shift the drivers and `driver block forwardly so that bythe time the plate 22 `has been raised to the elevation of the lower connection is again established.

The invention has'been hereindisclosed as Vembodied in a heel nailing machine but it is Withinthe scope -of theainvention to substitutev aivls for the drivers shown or otherwise modify the construction specifically described to adapt the machine for pricking heels instead of inserting and driving attaching nails.
